Car Driving Recorder Control Board
Details
As the new type of driving recorder gradually enters the market, its function is not only a camera for recording road conditions, it can also take pictures, share videos, navigate, connect with WeChat and QQ, and even detect the air quality in the car. If such a function can meet the needs of car owners, another blue ocean may be developed in this red ocean.
The driving recorder uses the main control chip to realize the recorder function, the common ones are Ambarella, Novatek, Allwinner, AIT, SQ, Sunplus, generalplus, Huajing Branch, Lingyang (Xinding), Taixin (STK), MediaTek (MTK), etc.
The working principle of the recorder is that the light passes through the optical lens and forms an image on the image sensor. The amount of these image data is very large (a 5 million camera will generate 450M to 900M of data per second). These data must be processed and compressed before they can be stored on the card, and there are many chips responsible for processing and compressing the data, that is, the chips of manufacturers such as Ambarella and Novatek mentioned above (similar to the CPU of a computer). In addition to data compression, these chips are also responsible for correcting and beautifying the image to make the image clearer. Generally, an automatic cycle, parking monitoring and other functions are also provided.
